Conceptual ramifications if black holes do not exist.

[ensabah6]

My question here is to ask what would be the consequences to theoretical physics if, it was discovered, that black holes do not exist in nature. For example, as gravity and pressure increases beyond neutron star, new, previously unknown quantum principles, similar in spirit to loop quantum cosmology, kick in, gravity becomes repulsive (or the quantum effects on the vacuum makes it anti-gravity) so that the object approaches but never crosses the threshold of black hole formation. This is somewhat analogous to what happens to the strong nuclear force, which gets weaker at shorter distances. As matter gets more pressure beyond neutron star, the quantum effects on the vacuum can no longer be ignored, and it acts like lambda, creating strong anti-gravity repulsive effects so black hole is never formed. In the interior, it is dominated by lambda not gravity.


Instead the object is a new, previously unknown, state of degenerate matter more dense than neutron star but not dense enough to form a black hole. Light is redshifted but could escape from the surface.

If true, would the holographic principle still apply? What about the current understanding of "black hole" entropy? Is QG needed to describe such objects or could some form of condense matter physics be more appropriate? What about black hole entropy? What about string theory, LQG, SUSY, extra dimensions?

The holographic principle is fundamental. Once its true nature is revealed it will explain a lot of things. The condition of the universe at different times could have had different coupling for the forces in effect( they could have even reversed signs).

here is an interesting article ,not directly related but gives you an idea. It is written by James Gilson, from Queen Mary.
